Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

When the hot rolled metal cools, it will reconfigure making the finished product with a looser tolerance when compared to the cold rolled metal. This looser tolerance makes it easier to force the metal into a variety of different shapes. Hot rolling is mainly used to produce simple cross sections or sheet metal.
